BRIDLE-BIT.

SPECIFICATION forming part of Letters Patent No. 390,567, dated October 2, 1888.

Application filed .Tanuariy 16, 1888. Serial No. 260,882. (No model.)

To all whom it may concern.-

Be it known that l, EDWIN R. CAHOONE, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Bridle-Bits; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of this invention is to reduce the cost of construction and to provide a more durable bridle-bit, preferably of the class of bits provided with vulcanized-rubber coverings on the mouth-pieces.

The invention consists in the improved bridle-bit having the arrangements and combinations of parts, substantially as will be hereinafter set forth, and finally embodied in the clauses of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several figures of the drawings, Figure l is a plan of the improved bit, showing the mouth-piece covering broken away, and thus illustrating the interior construction thereof. Fig. 2 is a detail view of the head adapted to engage the pivotal pins or bars of the cheek-pieces of the bit and to clamp and hold the ends of a certain core of the mouth-piece. Fig. 3 is a section taken on line X of Fig. 1. Fig. 4 is a section taken through line Y of Fig. 2. Fig. 5 is a view of the mouth-piece core before the same is arranged in the bit. Fig. 6 is a section of the head of the mouth-piece, taken on line Z, Fig. 4; and Fig. 7 is a section of the same, taken on line \V, Fig. 2.

In said drawings, 0, indicates the mouthpiece, and b b the cheek pieces of the bit. The latter may be of any suitable construction. Of the mouthpiece, c is a core consisting of a rope composed of twisted fibers or strands. Said rope may be,and preferably is, of metallic wire, although I prefer iron wire 0, interspersed with steel wires 0, the latter to add to the elasticity of the core. Said wires are given a simple twist, as distinguished from twisting groups or bunches of wiresinto strands, which are again twisted into rope. After twisting, the wires are dipped in tin at their extremities, and the wires are thus united at their said extremities, as at c 0'; but the middle parts are free to work, so that increased fiexibility is obtained, and at the same time greater durability.

d d are heads for holding the core to the cheek-pieces, which are adapted to receive bars or pins in said cheek-pieces, being provided with pivotal apertures e for that purpose. Said heads are also provided with clamp ing-arms ff, which are longitudinally concaved, as at g, to inclose or partly inclose the ends of the wire core and secure a neat covering for the ends of the wires and hold the strands together. The said concaved portions of the arms of the head are provided with inwardly- 7o projecting pins or lugs h, which are adapted to enter into or between the twisted fibers and prevent the core from being withdF-iwalongitudinally from the clamping-arms, the twist"- in the strands or fiber of the rope serving to prevent such longitudinal movement or withdrawal, as will be understood. The extremities of the arms, on the concaved sides thereof, are provided with ridges it to bite into the rope when the arms are clamped upon the same, and thus additional strength is secured at the union of parts. Said arms are also provided with abutments j, which prevent contact of the ends of the wires with the pivotal bar of the cheek-piece and also serve to give added security to the parts.

The arms of the heads when spread apart, as in Fig. 2, are adapted to allow of the ready insertion of the ends of the core, and are thus ready to be pressed upon the said ends, so that 0 when the rubber is molded on said core, to 10o,

have the rubber subjected to the heat employed in the vulcanizing process without damage to the said core. The said wire also allows of greater resilience than if the rubber covering were alone depended upon for that purpose. However, the use of rubber in connection with ordinary fibrous rope of hemp or similar material would provide sufficient resilience for some purposes.

While I refer to the rope as being of ordinary or simple twist or fiber, it is evident that the said strand may be plaited or braided without departing from the invention.

Having thus described the invention, what I claim as new is- 1. Theimproved bridle-bitherein described,

combining, with the cheek-pieces b b and'claniping-heads adapted to be compressed to inclose the ends of the rope, a rope of twisted fibers or strands having the ends held in said heads, and a suitable covering, substantially as set forth.

2. The combination, with cheek-pieces b b, and heads having pivotal apertures e and clamping-arms f, provided with pins or lugs a pivotal aperture, 0, and concaved clampingarms provided with pins or lugs h, substantially as and for the purposes set forth.

5. In a bridle-bit, a head having graspingarms concaved on the inside to receive the rope end and hold the strands together, and ridges at the extremities of the arms to bite into the wire, substantially as and for the purposes set forth.

6. In a bridlebit, the combination, with cheelrpieces Z) Z) and heads d, having pins h, formed in concavities g,ofa core oftwistedwires having tin or solder unions 0 at their opposite ends and free to work at their center parts, substantially as set forth.

7. In abridle-bit,in combination with checkpieces b b and heads dd, having an abutment, j, and pins it, formed in a concavity, g, twisted wires having solder or other unions, 0 c, at

their opposite extremities, substantially as srt forth.

8. In a bridle-bit, the combination, with cheek-pieces and a twisted core, of heads having concavities to receive the ends of the core, projections on the inner side ofsaid concavities to enterinto holding engagement with said core ends, and an abutment substantially as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 6th day of December, 1887.
